DN150 PN16 CF8M Thin Wafer Check Valve with Viton Seat Manufacturer & Supplier
ال Thin Wafer Check Valve DN150 PN16 CF8M Viton Seat is a compact, lightweight, and highly efficient non-return valve designed to prevent reverse flow in industrial piping systems. Featuring a wafer-style body design, this valve installs directly between mating flanges, significantly reducing installation space, weight, and overall system costs.
Manufactured from ASTM A351 CF8M stainless steel (equivalent to AISI 316 Stainless Steel), the valve offers exceptional corrosion resistance against seawater, chemicals, acids, alkalis, and industrial process fluids. The resilient Viton (FKM) seat provides bubble-tight shutoff, superior chemical compatibility, and excellent performance at elevated temperatures.
Designed for PN16 pressure service و DN150 (6 Inch) pipelines, this thin wafer check valve is widely used in water treatment plants, chemical processing facilities, food industries, pharmaceutical plants, marine systems, HVAC installations, and industrial utility networks.

Why Choose CF8M Stainless Steel?
CF8M is one of the most widely used stainless steel materials for industrial valves.
Corrosion Resistance
Provides excellent resistance against:
- Seawater
- Chlorides
- Acids
- Industrial chemicals
- Process fluids
Mechanical Strength
Maintains structural integrity under:
- Pressure fluctuations
- Temperature variations
- Continuous operation
Hygienic Performance
Suitable for industries requiring clean processing systems.
Advantages of Viton Seat Material
Excellent Chemical Resistance
Viton performs exceptionally well with:
- Petroleum products
- Aromatic hydrocarbons
- Synthetic oils
- Industrial chemicals
High Temperature Capability
Compared with NBR or EPDM, Viton offers superior performance in elevated-temperature applications.
Extended Service Life
The material maintains flexibility and sealing effectiveness over long operating periods.
Working Principle
The check valve operates automatically using flow pressure.
Opening Cycle
- Fluid enters the valve.
- Flow pressure pushes the disc open.
- Media passes through the valve with minimal resistance.
Closing Cycle
- Flow decreases or stops.
- Reverse pressure develops.
- Spring force pushes the disc closed.
- Backflow is prevented immediately.
This automatic operation protects pumps and process equipment.
